Spring boot 3 ehcache 配置设置问题

Question

我正在尝试在我的 Spring boot 应用程序中设置 ehcache。我有以下 ehcache.xml 和配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<config xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns='http://www.ehcache.org/v3'>
    <cache alias="myCache">
        <expiry>
            <ttl unit="minutes">60</ttl>
        </expiry>
        <heap>20</heap>
    </cache>
</config>

import org.ehcache.jsr107.EhcacheCachingProvider;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cache.jcache.JCacheCacheManager;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.cache.CacheManager;
import javax.cache.Caching;
import java.net.URI;
import java.net.URISyntaxException;

@Configuration
@EnableCaching
public class CacheConfig {
  @Bean
  public JCacheCacheManager cacheManager() throws URISyntaxException {
    ClassLoader classLoader = getClass().getClassLoader();
    URI ehcacheURI = classLoader.getResource("ehcache.xml").toURI();
    CacheManager cacheManager = Caching.getCachingProvider(EhcacheCachingProvider.class.getName()).getCacheManager(ehcacheURI, classLoader);

    return new JCacheCacheManager(cacheManager);
  }
}

但是，当我启动应用程序时，我收到以下错误消息：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cacheManager' defined in class path resource [com/webservice/config/CacheConfig.class]: Failed to instantiate [org.springframework.cache.jcache.JCacheCacheManager]: Factory method 'cacheManager' threw exception with message: javax/xml/bind/ValidationEventHandler

有人知道我做错了什么吗？看起来它与验证有关。所以我假设我的 ehcache.xml 文件可能不正确。我正在使用 org.ehcache.ehcache 版本 3.10.2。任何帮助将不胜感激。

Answer 1

您错过了一些有关验证的依赖项，请在项目中添加以下依赖项

    <dependency>
      <groupId>jakarta.xml.bind</groupId>
      <artifactId>jakarta.xml.bind-api</artifactId>
      <version>4.0.0</version>
      <scope>compile</scope>
    </dependency>
